ASPL 2pcs LED Warning Flash Beacon Lights, 60 LED Amber Warning Safety Flashing Strobe Lights with Magnetic and 16 ft Straight Cord for Vehicle Truck Tractor Golf Carts UTV Car Bus,12V-24V

Simply place the light in and plug it in. But don’t go faster than 45mph! I was doing city driving in Phoenix using these for Amazon package delivery and it scratched the roof of my car when driving.

I bought a pair of these for use on farm equipment. Very bright and visible. However, one quit working after less than an year, and -significantly- less than the advertised 50,000hrs of life. Disappointing. Maybe just one defective one?

very bright great strobe selections great price

I volunteer with a bicycling Club and doing root marking and following Riders on the course. The lights will be very helpful because I make frequent and sudden stops

I really like these lights. They are really bright and have several nice flash rates and patterns. I think they are a good value.

This is my third Flash Beacon since starting package delivery. The previous two lasted two months each before failure. Both, like this one, worked out of the box. Neither held up to a three-day a week job for two months. So I will report later how they work out. This one is a different company than the other two. And I am liking its look a lot. I prefer the straight cord for ease of maneuverability. This one has a long enough cord to use easily in my minivan (a constant problem). And I do like the two-for-one aspect of the purchase, since Ive resigned myself that buying new beacon regularly are a part of the job. Maybe these will prove me wrong! Start date is 1/7/2021 - but the job has cut back to once a week for the winter months - so it should last until the end of May to mid-June to match the use the others got during Thanksgiving and Christmas delivery season before dying. Ill report back when it fails. You dont see another comment, you know its all good.

I like the product, works good.

I read meters for a living. These are super cheap and get the job done. Brighter than I ever thought they would be even in daytime

Pretty cool! Kids loved it (used for a trunk decoration). Different light patterns and it sticks pretty well on the sides of the car!

Bought some time ago impressed. Resently put both strobes on a 1980 El Camino to draw attention to the truck in a parade. Personal classic truck of owner of salvage towing company. Visible from 1/2 mile away.
